Delphi NE Series Non-Isolated Point of Load

DC/DC Modules: 4.5~13.8Vin, 0.59V-5.1Vout, 20A

The Delphi NE 20A Series, 4.5V to 13.8V wide input, wide trim single

output, non-isolated point of load (POL) DC/DC converters are the

latest offering from a world leader in power systems technology and

manufacturing —Delta Electronics, Inc. The ND/NE product family is

the second generation, non-isolated point-of-load DC/DC power

modules for the datacom applications which cut the module size by

almost 50% in most of the cases compared to the first generation NC

series POL modules. The NE 20A product family provides an ultra

wide input range to support 5V, 8V, 9.6V, and 12V bus voltage

point-of-load applications and it offers 20A of output current in a

vertically or horizontally mounted through-hole miniature package and

the output can be resistor trimmed from 0.59Vdc to 5.1Vdc. It

provides a very cost effective, high efficiency, and high density point

of load solution. With creative design technology and optimization of

component placement, these converters possess outstanding

electrical and thermal performance, as well as extremely high

reliability under highly stressful operating conditions.
